Our observation that the single copy for Kerr-NUT-(A)dS black holes is an aligned field is not restricted to \(D =5\) . Previously known single copies for \(D = 4\)  Schwarzschild, Kerr and Taub-NUT spacetimes[1]}, [2]}, [3]} (all of which are in the Kerr-NUT-(A)dS class) are also aligned fields, as we
now briefly demonstrate.
